Re: Quenching autofluorescence

As an aside to the rbc autofluorescence problem, red blood cells 
from patients with erythro-protoporphyria fluoresce red.  My limited 
experience of two cases suggests it would be unduly problematic 
anyway - it is the deuce of a job to visualise the poor signal.

I occasionally show an old photo. of a rat model for the disease, 
with its incisors fluorecsing vry brightly under UV light.

The disease is believed by some to have manifestations which have 
led to the belief in the "werewolf".  Hirsuitism is another 
characteristic of the disease.
